Older But Young at Heart

I'm fifty-five and have only recently admitted to myself that I find the idea of being taken care of by a younger partner incredibly appealing. Last month, when my friend's nineteen-year-old son came over for dinner, something about his confident demeanor and the way he effortlessly handled everything around him sparked an unexpected attraction in me. It wasn't sexual per se, but there was this undeniable thrill from imagining myself as someone needing more guidance and care from him. Of course, it's all just silly daydreaming because I know we're both grown-ups with responsibilities, or am I the only one who ever thinks about something like this? Is it common for folks my age to have such youthful fantasies? Any advice on how to channel these thoughts in a healthy way without getting too carried away?
